ABSTRACT:
This gas engine with pre-combustion chambers effectively uses ejection energy of flames and air-fuel mixtures ejected from the pre-combustion chambers into the main combustion chambers to shorten the combustion duration and thereby enhance performance. Installed in the cylinder head at the central part of the cylinders are pre-combustion chamber structures that form pre-combustion chambers. Combustion chamber structures are formed with communication port that communicate the pre-combustion chambers with the main combustion chambers. Control valves are provided to open and close the communication ports. The communication ports comprise main communication ports and sub-communication ports formed around the main communication ports. The sub-communication ports are formed in the combustion chamber structures so that they extend radially toward the cylinder periphery.
